For purposes unrelated to railroading, I was reading this article, which pertains to the history of driving on the left or right side of the road. About half way into that article is a section regarding trains. This may be old news for you experienced folks, but it was news to me. I thought folks may be interested in this particular excerpt, if you’re modeling C&NW:
In the USA and Canada, trains keep to the right, with one major exception: the Chicago and Northwestern Railroad. The line’s construction was financed by British capital, which may have influenced the track plans. It may also be that the stations were arbitrarily placed all on one side of the tracks when the line was single-track, and when the second track was added it was impractical to change all the station alignments so the outbound track ended up on the left. (Don Howard, Eric Zimmerman) Another exception can be found in the approaches to New York City’s Grand Central Station, which were run left-handed around 1900 because the new arrivals section of the terminal was built on the only available land, on the wrong side of the tracks. The crossing point was several miles north of the station, away from the worst congestion.
